GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 256,188, dated April11, 1882, Application filed January 31, 1882. (No model.)

1 '0 all whom it may concern.-

Be it known that 1, JOHN F. APPLEBY, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Grain-Binders;

-and 1 do hereby declare that the following is a full, clear, and exactdescription thereof, ref erence being had to the accompanying drawings,making partof this application.

Myinvention relates to an improved contrivance or means for insuring thestoppage at the right time and in the right position relatively to thedriving mechanism thereof of thegears through which power and motion areimparted periodically to the binding mechanism proper of that kind ofgrain-binders in which the grain passes into and is packed in agavelreceptacle, and the gavels or collected masses are periodicallytied up into sheaves and automatically discharged from the machine.

In Letters Patent granted to me February 18, 1879, No. 212,420, is showna machine of this class, and to this kind of machine, in the improvedform in which I have lately used it, I have shown my present improvementapplied.

As heretofore constructed this kind of machine has embodied the defectofa constant liability to make considerable noise, and have much wearand tear on some of the parts, as well as a liability to have theintermittinglymoving parts stop out ofti me and out of place, owingtothefacts,first, that the driving device, when thrown out of engagementwith the pinion fordriving the binder mechanism proper, left said pinionin a position to have the said con tinuously-running driving device comeinto contact with or strike against the part of said pinion lastinworking engagement with said driving device; and,second, that under thedegree of resistance to which the parts of the binder mechanism properare often subjected said parts would be turned scarcely to the properpoint, or, if so turned, would spring or yield back slightly whenreleased from the drivingpower.

My present invention has forits main objects to overcome these defectsand render the kind of grain-binders to which said invention isapplicable capable of working better; and to this to end and object myinvention consists in the combination, with the gear on the cam and rackwheel shaft, ofa springmotor contrivance adapted, as will be hereinaftermore fully explained, to cause a given degree of movement of the partsof said mechanism after it shall have ceased to be affected by the usualdriving device,'whereby not only are the parts of the binder mechanismall carried to and stopped always at precisely the proper point, butwhereby, also, the carrying of the gear, acted on by thecontinuously-rnnning driving device of the harvester, to a pointat whicha complete clearance of said driving device will be insured is certainlyeffected To enable those skilled in the art to fully understand andpractice my invention, I will now proceed to more fully describe it,referring by letters to the accompanying drawings, in which Figure 1 isa partialside elevation ofa grainbinder such as made the subject of mysaid Letters Patent above referred to and as improved and used by me upto the time of my present invention. Fig. 2 is a similar view, showingmy present improvement applied to said machine, and so much only of thesaid machine as it seems to be necessary to show. Fig. 3 is a similarview of the devices seen at Fig. 2, but with the parts in a differentrelative position; and Fig. 4 is a detail sectional view at the line 00a: of Fig. 3.

In the several figures the same parts will be found designated by thesame reference-letters.

With reference to Fig. 1, I need only state that the parts therein shownare about the same as and operate in like manner to the parts of my saidpatented machine as now used by me, and that 'E is the main gear on thecam and rack wheel shaft S, and is driven from the continuously-rotatingshaft M of the machine through the media of the intermediate pinions orgears, E E and a spur-pinion loose on shaft M, but periodically clutchedto 5 said shaft by the dog P, against which work the driving-projectionst of' the continuouslyturning face-plate 0, all as already well known.

In carrying out my present invention I erely cast the part A (seeFig. 1) of my mab and a collar, whenever the said rod may chine with asort of extension, as seen at A of Figs. 2 and 3, and vary the form ofthe casting of gear-wheel E, so as to have it formed with a cam-likerib, as shown at E Figs. 2 and 3, and I then apply the necessaryadditional devices as follows:

b is a metallic stand or piece, formed with a projection at I), in whichis hung one end of a rod, 0 the other end of which is pivoted to alever, 01*, the said stand I) being bolted to A and having a laterallip-like projection, b ,(see Fig. 4,) thatunderlies and bearsagainst aportion of the lower edge of the portion A of casting A. On the rod 0 isa spiral spring, 0 which is compressed between the projection be pushedthrough projection b in the direction indicated by the arrow at Fig. 2and into the position seen at Fig. 3. The upper end of arm (1 is coupledto one end of a rod, f, the other end of which has an oblong eye, f thatco-operates with two eye-pieces at g, for a purpose to be presentlyexplained, and said arm d carries at c a small anti-friction roll,whichacts on the cam E of wheel E in amanner and for the purpose to bepresently explained. The height of the roller at e relatively to theaxis of wheel E is easily and nicely adjusted or fixed in putting themachine together by cutting and fitting together the lip-like part b ofstand b and the edge of A that fits to said part I)", the stand I)turning slightly to permit any necessary adjustment by reason of itspivotal connection at '6 and the curved slot (seen in dotted lines atFig. 2) in the part A When properly fitted or adjusted the bolt at isscrewed up and the parts I) and A securely fastened together.

The operation is as follows: Supposing the parts to be in the relativeposition seen at Fig. 2 and the wheel E to be turning as per arrowindicating its direction ofrotation. when the cam-like rib E comes intocontact (not far from its end 2) with the roller at c said roller andthe arm d will be caused to vibrate about the axis of bolt j and in thedirection indicated by the arrow at Fig. 2 until the point z of cam Eshall have passed by the bearingpoint on the periphery of roller c atwhich any movement of the arm d in the reverse direction (indicated byarrow at Fig. 3) will exert a tendency on the part of said roller topress the cam E in the direction in which wheel E has been thus farmoving. At this point the driving devices (at shaft M, Fig. 1) becomedisengaged, so as to cease to drive the pinion E and but for other meansof movement the wheel E would now stop. The pushing tendency of roller 0now, however, comes into play, and, actuated by the powerful spring 0which has been compressed, the arm (1 vibrates in the directionindicated by arrow at Fig. 3 and into the position shown in said figure,thus causing a slightfurther movement of wheel E and all partsinfluenced by its movements into a position just such as re- I quired,and in which the engaging surfaces of the driver and the driven devicesat shaft M will perfectly clear each other. derstood that as soon as theparts shall haye been thus forced into the relative position just statednot only will the spring 0 have expended by expansion its greatestforce, but the roller 0 will have come to a sort of abutment or stopagainst the ascending surface or portion of the face of cam E(represented at Figs. 2 and 3 by the circular dotted line,) whereby anyfurther movement through the tendency of the spring 0 is avoided.

When the intermittingly-moving parts of the machine are at rest in thepositions shown at Fig. 3 the eye f of rod f is in such relationshipwith the stationary eye 9 (between which eye f is located and moves)that the binder-cord, which passes through all of the said eyes, willnot be ali'ected; but when the intermittin'gly-movingparts shall havestarted off on another movement, and at the beginning of said movementallowed the arm d and rod f to have been forced by spring 0 into theposition seen at Fig. 2, then the eye f will be moved to a position suchthat the cord, passing through all three of the eyes referred to, willbe pulled into a triangular shape by pulling oft'a larger .supply fromthe ball, and when the parts again resume the relationship seen at Fig.3 there will be a certain amount of slack, which may be most easilytaken up by the binder devices proper in tying a sheaf, and which alsoserves to prevent any jerk or strain on the cord as the needle-arm(through an eye in which the cord pa ses, as usual) and other parts allcome to a sudden stop. Thus I make the same means which I employ toactuate the gears and force them to stop at just the right time andplace act also to operate the slack-making device of the binder. Saiddevice is not new in itself in my present machine, but is applied andoperated in a novel manner, asjust explained.

What I claim as new, and desire to secure by Letters Patent, is

1. In combination with the intermittinglymoving mechanism of the binderand the continuously-runningand automatically-unclutching driver devicesthereof, means, substantially as described, for causing a slight furthermovement of said mechanism after its releasement from the influence ofthe said driver devices, as set forth.

2. Incombination with the automatic mechanism for causing the bindermechanism to move on after its releaseinent from the influence of thedriver devices of the machine, a rod,f provided with an eye, f and twostationary eyes, 9, the whole arranged to operate substantially as andfor the purposes set forth. In testimony whereof I have hereunto set myhand this 12th day of December, 1881.
